Abstract
The invention relates to a latching device for an operating mechanism (100) for an electrical switching apparatus. The device has a locking member (1) movable between a first position and a second position.In the first position the locking member (1) is arranged to lock a drive member (101) of the operating mechanism (100) in a locked position,and a force (F) of the drive member (101) being applied to a contact portion (11) of the locking member (1). In the second position the locking member (1)is arranged to release the drive member(101) from the locked position. At least in the first position the locking member (1) is arranged to bear against the counter roller. A tripping member (3)is movable between a first position locking the locking member (1) and a second position releasing the locking member: According to the invention the locking member (1) has a first portion (12) and a second portion (13). The first portion is rotatable connected to a first link (4) around a first pivot axis (P1), which first pivot axis (P1) is movable perpendicular to its direction. The second portion (13) is rotatable connected to a second link (5) around a second pivot axis (P2) and movable perpendicular to its direction. The second link (5) is rotatable connected to the tripping element (3) around a third pivot axis (P3). Movement of the tripping member (3) from its first position to its second position initiates movement of the contact portion (11) out of force- transmitting relation with the drive member (101). The invention also relates to an operating mechanism provided with the invented latching device.
